Enable debug symbol propagation 

The existing code was sufficient to pass through
and relocate most debug symbols as necessary. It
was just disabled for some reason. The only bugs
were in the handling of non-text line numbers,
which aren't ever used as far as I can tell, and
include files, which should be relocated like
line numbers to match ALN's behavior.
